MACHINERY FOR RUBBING TYPE.

SPECIFICATION forming part of Letters Patent No. 457,575, dated August 11, 1891. Application filed October 11, 1890. Serial No. 367,825. (Nomodel.)

To all whom it may concern.-

Be it known that we, JAMES C. BIRCH and CHRISTIANDANCEL,bOtl1 citizensof theUn ited States, residing at Brooklyn, in the county of Kings andState of New York, have invented an Improvement in Machinery for RubbingType, of which the following is aspecification.

In Letters Patent No. 380,599, granted April 3, 1888, to George S.Eaton, assignee of George S. Eaton and James (J. Birch,a mechanism isrepresented for receiving type and passing the same along between twopolished surfaces to equalize the type at the same time that the cuttersremove from the base of the letter the projecting burrs.

The present invention is an improvement upon the devices set forth inthe said patent; and the same consists in the peculiarities ofconstruction and combination hereinafter set forth and claimed.

In the drawings, Figure 1 is a plan view perpendicular to the inclinedbed. Fig. 2 represents the bed-plate with the parts above the sameremoved. Fig. 3 is a section of the equalizers and bed near the line x{I}; and Fig. 4: is a plan of the feeding mechanism with the bed insection near the line y 1 Fig. 3. Fig. 5 shows the feed-plate andsteadying-finger.

Fig. 6 is a detached view of the slide and bolt.

from the under side and in larger size, and Figs. 7 and 8 show the leverand plate for the adjusting-screw of the equalizer.

The frame A, driving-shaft B, and bed C are similar to those in theaforesaid patent, and upon the bed 0 is a plate D extending up to thetable D,u pon which the types to be rubbed are placed, and this plate Dis perpendicular to the bed 0; but the bed and the plate are inclined tothe horizontal line at about fortyfive degrees, and the stationaryequalizer E.

is bolted permanently to the bed 0, and the movable equalizer F isadjustable toward or from the stationary equalizer E and between theguides G, that are permanently fastened upon the bed 0, and there is ascrew 1'' for adjusting the equalizer F toward and'from the equalizer E.These parts, except as hereinafter named, are also similar to those inthe aforesaid patent.

In practice we have found that in cases where an imperfectly-cast typewas forced in between the equalizers and the machine was stoppedthereby, the belt slipping upon the pulley V it was difficult to removesuch obstruction without altering the adjustment of the movableequalizer in its relation to the stationary equalizer. To provide forthis contingency we make upon the screw f a rigid collar 5, which isadjacent to the bearing 6, through which such screw f passes. Thisbearin g 6 is permanently fastened to the plate 0, and the distancebetween the rigid collar 5 and the side of the bearing 6 is such thatthe movable equalizer F can he slipped away from'the stationaryequalizer E until the collar 5 strikes against the side of the bearing6, and this movement can be given to the parts after the lever 7 hasbeendrawn back, there being upon this lever 7 a plate 8, the end of which isslightly beveled and notched, so as to pass over the screw f and betweenthe rigid collar '5 and the bearing 6. Hence when the machine is inoperation the pressure in equalizing the types is taken by the collar 5upon the plate 8 and bearing 6, and when this plate 8 is raised by thelever/ the equalizer F can be moved back and any obstruction taken outfrom between the equalizers, and in doing this the screw f is notretated, nor the adjustment varied in the least, and the parts arereturned to their normal position by pressing the plate 8 in between thecollar 5 and the bearing 6.

In the aforesaid patented machine the base of the type rested upon thesurface of the bed 0, and the pusher I moves such type along with thebase thereof in contact with the surface of said bed. It has been foundthat the delicate edges of the base of the type are sometimes injured bythe friction of the base of thetype against the surface of the bed 0. Toavoid this difiiculty, we make use of a traveling table 9 within a slot10,, that extends from the place of reception to the place of deliveryof the types, and this traveling table 9 is connected with and moved bythecarriage N, that is supported by the portion (J of the bed 0. Thiscarriage receives its motion in' substantially the manner described inthe aforesaid patent, and it also carries the pusher I, which isconnected to it, as before described, and the operative end of thispusher is immediately over the traveling table 9. Hence each type, as itis fed into the machine, passes down and its base rests upon this table9, and the pusher I carries the type along between the equalizers E andF, by which'the surfaces of the type are smoothed and such typeequalized, and during this operation the cutters M remove the burrs fromthe base of the letter, and during this time the base 'or lower end ofthe type rests upon the table 9, and this table 9 sets up closelyagainst the lower edgeof the movable equalizer F. Hence such equalizersact efficiently upon the whole of the surface of the sides of the typeduring the operation of equalizing and rubbing.

In the aforesaid machine the surface of the equalizer F in line with thefeed was notched to allow for the type feeding down between the twoequalizers with freedom. We find it advantageous to make theequalizing-surfaces upon the equalizers E and Fsmooth and flat, andinthe block portion of the stationary equalizer E in line with the feed arecess is provided for the feeder 11, which is in the form of a blocksufficiently wide to correspond with the widest type, and it receives amotion from the line of the face of the plate D up to the face of theequalizer E, and this motion is given to the feeder by avrod 12 andlover P upon a fulcrum 14, and this lever is acted upon by a cam (shownby dotted lines in Fig. 3) and a spring 14, and this rod 12 isscrew-threaded and provided with locknuts 15, which come up against theback surface of the stationary equalizer E, and they are so adjustedthat when in contact there with the face of the feeder is accurately inline with the polished surface of the equalizer These lock-nuts allowfor adjustment in case of wear, and there is a spring 16 between the jawend of the lever P and the lock-nuts 15, so that the cam upon thedriving-shaft B will act to compress this spring after the locknuts 15come into contact with the rear surface of the equalizer E and the nuts17 are behind the jaw of the lever P and they are adjustable, so thatwhen the jaw of the lever P comes in contact with the metal at the endof the slot in the bed 0 the surface of the feeder 11 will correspondaccurately with the surface of the plate D. The plate D is set back.from behind and below the surface of. the equalizer E a distance equalto the largest 'end to a small plate connected to the surface type towhich the machine is adapted, so that the type may be fed down thisplate D and'in front of and rest upon the feeder 11 during the time thatthe pusher I is carrying the preceding type through the machine. Thisallows more time for the operation of the feeding mechanism, and whenthe type is brought up to position it is held reliably between thesurface of the feeder 11v and the polished face of the movable equalizerF, so that the pusher I acts uniformly in starting the type andcarryingit through between the equalizers and during the rubbingoperation. We find'it preferable to make use of automaticspring-pressure for detaining the types 'a slide 21 connected with themoving end of said lever 19 and adjacent to the lower edge of theplateD, and in a recess at the end of this slide 21 is a bolt 22,sliding freely but kept toward the type by a weak spring 23 and there isa second-lever 24, pivotedat25 and acting to draw backthe presser 26,and there is a contractile spring 27 acting upon the presser in theopposite direction. It;w-ill now be understood that theattendantisupplies the types successively between the guides q q anduponthe table D and the presser 26 arrests their downward movement. At theproper time the presser 26 is drawnback by the lever 24, so that thetype can slide down upon the plate D, and betweencthe guides q q, andsimultaneously with this movement,whichdraws-back thepresser26,the slide21 is moving in the opposite direction and the bolt 22 passes across theslot between the guides q q and the type is arrestedthereby, and thisbolt 22 is drawn back at the proper moment to allow the t ype toslidedown upon the surface of the feeder 11 before said feeder carriesthe type up against the surface of the equalizer F, as aforesaid, andshoulda type become obstructed or temporarily detained between theguides q q, or should the attendant supply the types too fast betweensuch guides, the type will not be injured by any positive motion givento the parts, because the presser 26 is moved toward the types by thecontractile spring 27, which is too weak to injure the types, and thebolt 22 is moved toward the types by the slide 2l'and'the spring 23.Hence the types are not injured,.even when very thin, by being caughtbetween the end of either the. bolt 22or the presser 26 and the guide q,and the feeding operation is uni: form and reliable.

The steadying-finger 7c is pivoted at its lower of the equalizer F,similar to that in aforesaid patent, and this steadying-finger lies inthe slot between the guides q q and above the types, and there is aflexible spring 28 to press such steadying-finger to its position with aslight force; but the plate that carries the pivot of thesteadyingwfinger, is slottedfor the screws by which it is connected tothe equalizer F, and a spring 29 tends to press the block 70 away fromthe table D, and there is a screw 30 with a conical shank adjacent tothe edge of the plate is, so that by screwing thisscrewv 30 downwardlyand into the equalizer F the steadying-finger it will be moved towardthe plate D, and when the screw is turned in the other direction thespring 29 moves such finger it; away from the plate D, giving more roomfor the types that are fed between the guides q and q. I

The stationary block S, with a curved end to guide the type as it isdelivered from the machine to a rule or holder '1, is similar to that inthe aforesaid patent, and theblade r carries the type into the groovebetween S and S; but in order to allow the traveling table 9 to carrythe types to the place of delivery such table 9 is preferably made as athin plate, as shown in Fig. 41 110 pass over the beveled surface of thebed 0 at the place of delivery of the types, and the parts are to be sotimed that the table pauses at the end of its movement and the blade rcarries the type off the table 9 and in between the blocks S and S andholds the same in its position while the table 9 commences its returnmovement, thus entirely preventing the movement of the table 9 frominterfering with the proper delivery of the type from the machine.
